LOOM-SHUTTLE.

Specification of Letters Patent.

Patented Jan. 23,1912.

Application filed June 11, 1909, Serial No. 501,481. Renewed December 12, 1910. Serial No. 596,970.

To all whom it may concern:

Be it known that I, ALBERT B. Wnrssn1v- BORN, residing in Appleton, in the county of Outagamie and State of Wisconsin, have invented new and useful Improvements in Loom-Shuttles, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

iso

This invention has for its object to provide a shuttle designed for use in wire weaving looms, though novel features thereof may be used in shuttles generally.

One of the main features of novelty of this invention is a bobbin holder which may be swung from one position to another so as to stand in the same relative position to the front end of the shuttle in either direction of movement thereof.

Another main feature of novelty of this invention is the provision of means for shifting the axis of the rollers on which the shuttle travels to cause the shuttle to hug close to the reed in traveling in either direction, this means being preferably,,though not necessarily, operated by the swinging movements of the bobbin holder.

Another feature of novelty in the present invention is a pivoted bobbin supporting stem which is normally locked in its closed position-but which may be easily swung open to permit of the bobbin being quickly and easily placed thereon, the bobbin bemg automatically locked on the stem when the stem is turned to its closed position.

The invention has the above features of novelty as its objects and has the further object of providing various details of construction incident to such features of novelt desire it to be understood that this invention is not limited to any specific form or arrangement of parts except insofar as such limitations are specified in the claims.

With the above and other objects in view the invention consists in the shuttle herein shown and described its parts and combinations of parts and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in the different views; Figure 1 is aplan view of a shuttle constructed in accordance with this invention; Fig. 2 is a bottom view thereof with a part broken away to show the spring for a roller frame; Fig. 3 is a similar view with the showing the engagement between the bobbin holder and the roller frame; Fig. 5 is an enlarged transverse sectional view on the plane of line 55 of Fig. 1; Fig. 6 is a detail view of the pivotal screw for the roller frame; Fig. 7 is a bottom view of the shuttle with the bobbin holder and the bobbin in section and a portion of the shuttle body in section; Fig. 8is a front elevation of the shuttle with the bobbin holder in the act of changing from one position to the other; Fig. 9 is a plan view of a portion of the shuttle showing the bobbin stem turned to its open position for replacing the bobbin; and, Fig. 10 is a transverse sectional view of the shuttle looking toward the eye of the bobbin holder.

In these drawings 10 indicates the shuttle body mounted upon the rollers 11 which are slightly obliquely disposed, as shown, and which are adapted to, be shifted in position to cause the shuttle to hug the reed during its travel in either direction. Each of the rollers 11 is mounted in a U-shaped roller frame 41 by having the conical trunnioned ends of its axle 42 fitting in correspondingly shaped recesses or sockets in plugs 43 and 44 in openings in the-ends of the roller frame 41. The rollers 11 with their frames are contained within openings in the ends of the shuttle body and the frames fit within slots 45 in the sides of the shuttle body which i,

form guides therefor. The plug 43 is locked in position in the frame by having the pinlike end of a pivot screw 46 passing through it and through the end of the roller frame 41, said screw being threaded in the shuttle body and serving as a pivotal connection on which the roller frame 41 may swing to give the roller either of the oblique positions shown in Figs. 2 and 3. The plug 44 is threaded in the roller frame so as to adjust the fit of the roller in its bearings. A coil spring 47 is provided for each of the roller frames 41 and connects the free end thereof to a screw 48 or other means of connection on the shuttle body to give the roller frame the normal tendency to swing to its innermost position, as shown at-the right of Fig. 2, said spring 47 being contained within a bore or drill opening in the shuttle body.

The central opening 12 in the shuttle body 7 contains a reversible bobbin holder 13, which is pivotally mounted on the slanting reed side of the shuttle by means of a pivotal connection 14 with its pin passing through an opening in the side of the shuttle and riveted to a washer 15 countersunk on the outside. The heavy metal strip forming the main portion of the bobbin holder and the lighter strip 16 carrying the guide eye 17 are riveted or otherwise suitably secured together so that the entire bobbin holder swings on the pivotal connection as a fulcrum. At each end of the central opening in the shuttle body is a stop plate 18 closingthe upper end of a slot 19 and engaged by the projecting end of the member 16 to limit the movements of the bobbin holder in either direction, said end of the member 16 being rounded and serving as a cam to engage and swing either of the roller frames 41 against the action of its spring 47 and then being limited in its movement by its engagement with the stop plate 18 where it will be held against rebounding by means of the spring retracted roller frame 41 as shown in Fig. 4.

A stud or boss 20 is carried by the end of member 13 and a sleeve 21 is loosely mounted on the stud and is held with spring pressure against the member 13-by a coilspring 22 secured to the end of the stud and bearing on the sleeve, said sleeve being provided with a stem or pin 23 to receive the bobbin 24 having the wire 25 or other weaving filament wound thereon. The sleeve 21 is provided with a flange 26 at its base which contains an opening to receive a pin 27 projecting from the member 13 and thereby locks the sleeve against turning on the stud when the pin 23 is directed toward the eye 17. Another pin 28 projecting from the member 13 enters an annular groove 29 in the base of the bobbin 24 when the sleeve is turned to the position in which it is locked by the pin 27, and thus serves to prevent the removal of the bobbin from the pin23. In order to move the bobbin it is only necessary to draw the sleeve 21 against the action of spring 22 so that the opening in the flange 26 is freed from the pin 27 and'then turn the sleeve so as to carry the bobbin away from pin 28 and out of alinement with the eye 17. The bobbin may then be removed and replaced by another and as soon as the sleeve is swung back to its normal position the spring 22 causes it to snap over the pin 27 when the opening is in register therewith 1 and at the same time the pin 28 enters the groove 29 of the bobbin to lock it in place.

The end of the bobbin is provided with a spherical head or enlargement 30 which prevents convolutions of wire being prematurely drawn off the bobbin by the pull upon the unwinding convolution, and further serves as a guide for the wire .when it is unwinding from the smaller end of the bobbin requiring the pull thereon to be somewhat outwardly instead of more directly in line with the axis of the bobbin, as would otherwise be the case, thus preventing the wire being drawn sharply against the smaller convolutions as the unwinding approaches the smaller end of the bobbin. Without the head 30 the convolutions at the smaller end of the bobbin would be liable to be drawn ofi of the bobbin with the unwinding convolutions and form a tangle, also the bend of the wire at the smaller end of the bobbin as the unwinding of the convolutions approaches the end of the bobbin would be so sharp as to bind upon the end convolutions to either entirely prevent the wire being drawn off or to interfere with the travel of the shuttle so as to interrupt the work.

To enable the wire being drawn directly from the bobbin in either direction of movement of the shuttle there is a slot 31 inthe side of the shuttle terminating in inclined slots 32 at the ends thereof 'and the wire switches from one end of the shuttle to the other through the slots so that with the turning of the bobbin holder the wire is fed off of the bobbin in the same manner and under same conditions during both directions of travel of the shuttle.

The swinging of the bobbin holder at the end of the movement of the shuttle in either direction may be accomplished in any desirable manner, either by hand or by suitable mechanism, such as that shown in my Letters Patent No. 978,248 for looms, dated December 13, 1910, and by reason of its placing a greater weight at the front of the shuttle it serves to assist in causing the shut: tle to travel in a straight course. By reason of the bobbin being directed toward the rear of the shuttle in its travel in either direction the unwinding of the wire therefrom is greatly facilitated; Also because of the bobbin holder carrying with it the guide eye 17 the wire is caused to be drawn ofi in the line of axis of the bobbin at all times. The

shifting of the bobbin holder from one posi tion to the other accomplishes the change in position of the rollers sothat whenever the bobbin is in position for the shuttle to move to the right the rollers are likewise in a position to cause the shuttle to tend to ride to ward the reed and thus assure its traveling in the proper course. When the bobbin holder is swung to the other position for the travel of the shuttle to the left the rollers are changed accordingly so that the tendency of movement of the shuttle is still toward the reed. In either position of the bobbin holder the rollers stand approximately parallel to each other as shown in Figs. 2 and 3.

What I claim as my invention is: 1. A shuttle having a. pivotally mounted bobbin holder adapted to be swung from one position to a reverse position to cause the bobbin to stand in approximately the same relation to the direction of travel of the front of the shuttle in either direction of movement of the shuttle.
